The Brief Self-Control Scale (BSCS), Paranoid Thought Scale (GPTS), and Emotionality (PANAS) were scored from 0 to 4; Conspiracist Mentality Questionnaire (CMQ) was scored from 0 to 10; Paranormal Belief Scale (PBS-R) and Intolerance Uncertainty Scale (IUS) were scored from 0 to 6; Interoception (MAIA) was scored from 0 to 5, and Schizotypy Personality (SPQ) was scored in a binary manner (1 if “Yes”, 0 if “No”). The greater the scores, the stronger the traits of interest.
